I have run sudo /usr/local/sbin/maintain-replica-indexes --debug --database satwiki on all 3 wiki replica hosts.

@Bstorm I can't finish this one due to pymysql.err.OperationalError: (1044, "Access denied for user 'maintainviews'@'localhost' to database 'satwiki\\_p'") on all 3 hosts. Your root powers are required.

Created the _p database for this. @bd808 if you are very bored, you can finish it now (DNS should already be set). I can get it myself later otherwise. Because of that bug, these all need both the grant and the _p database created on every replica.
